I'm posting this on behalf of my daughter who is being treated by Dr Peatfield for CFS and fibromyalgia. He had put her on NutriAdrenal but after taking it for about 2 and a half months and building up to 5.5 she doesn't feel that it's helping and is wondering whether to try Cortes. Unfortunately Dr P seems unavailable at the moment so she can't get advice from him and she's almost out of NutriAdrenal so needs to make a decision quickly. Please can someone advise on this, and also on reputable sources of Cortes if she does decide to try it. You can PM me if necessary and I'll pass on the info.
